I overthink language generally, and one result of such overthink is my affection for the use of the word "douche" as an insult. Such use is relatively modern; furthermore, no one seems to know what it's supposed to mean.
The fact that it's an innocuous French word meaning "shower" is irrelevant. In American English, "douche" always carries its "feminine freshness" connotation. Therefore when "douche" is used as an insult, it's obvious to me what it means, and what it means is exactly what makes it a genius insult. It's a matter of medical consensus that douching is useless at best, and more likely harmful. So there you go. Next time you reflexively call someone a "douche," you might be surprised to find out how well the description of "useless at best, harmful at worst," applies to said person.
Furthermore, one has the option to more specifically insult someone as a "douche nozzle" and "douche bag,"
